23 Claims.

This invention. relates to liquid dispensing apparatus, andv moreparticularly to liquid fuel stoves orheaters incorporating suchapparatus.

The present invention is based on the same principle as that whichcharacterizes the joint invention of myself and John A. Dahlstrom, setforth in our co-pending application Serial No. 305,506, filed November21, 1939. The principle to which reference is made is present where areservoir, having an opening, is placed on a support with said openingin an elevated position and moved. in an approximately horizontaldirection, with a progressive end-over-end action, to an invertedposition over a distributing recepta'cleor basin with said opening indischarging relation thereto.

f A purpose of the present invention is to reduce thedistance traveledby the reservoir in the accomplishment of a substantially completeinversion; and another object is to render positive the traction betweenthe bearing portion of the movable structure comprising. the. reservoirand the element or support along which. it moves.

Among the more general objects of the invention are simplicity andcompactness of construc tion and convenience of use, alllof which willmore fully appear from the following description taken in conjunctionwith the accompanying drawings wherein Fig. 1 is a side elevation of aliquid fuel heating stove incorporating the invention with a part of thestove casing broken away and other parts shown in section; Fig. 2 is afragmentary plan view, partly in section; Fig. 3 is a perspective viewof the reservoir; Fig. 4 is a sectional rear elevation of the stove, theplane of section being indicated by the line 4-4 of Fig. 1;

Fig. 5 is a similar view of the stove showing the door to the reservoircompartment swung down to open position with the reservoir restingthereon in upright position, the reservoir being indicated in invertedoperative position by dot-anddash lines, and Fig. 6 is a perspectiveview of one of the supporting elements or rails on which the reservoiris moved between its substantially upright position and its invertedoperative position.

The stove casing I, equipped with a closure 2 at the front, encloses acombustion chamber 3 having an annular bottom wall 4, below and inspaced relation to which is supported a burner bowl or firepot 5, suchconstituting the burner proper. To the rear of the casing I is a housingIll that encloses a reservoir compartment at the bottom of which islocated a distributing receptacle or fuel basin I2, Extendinghorizontally across the top of the basin is a removable plate l5 havinga'depressed central portion l6 whose peripheral wall is provided withscreened openings ll. The distributing receptacle or fuel basin l2communicates with the burner bowl .or firepot through a conduit 20,including a metering valve 2|, the operating handle 22 of which isdisposed above the top of thehousing ID. A flexible element (not shown)for cleaning the conduit 20 is connected to the lower end of a rod 23that extends downwardly through a central aperture of the handle 22' andthrough thehol low valve stem to which the handle is attached, and isnormally held in retracted position by a spring 24 that is confinedbetween the top of the" handle 22 and an abutment 25 on the rod 23. Theforegoing structure constitutes no part of my present inventionexcepting in a general way in certain combinations, and further detailsof a stove-of the same character may be had by ref- As will appear fromFigs. 2, 4 and 5, the housing I0 is open at one side, and hingedlysupported in closing relation thereto is a door 30. The door isdesirably hinged adjacent its lower edge to the housing through themedium of a pintle 31; and it is urged toward and held in closedposition by suitable spring means, as by a tension spring 33 that hasone end anchored to apart 34 adjacent the closed side of the hous-' ingand its other-end connected, through a link 35, with a part 36 onthedoor. An ear'31 extends from the free edge of the door and serves as astop to limit the movement of the door in closing direction by contactwith the adjacent edge of the housing and also as a convenient fingerpiece for swinging the door downwardly to open position, as shown inFig. 5, in which position it is stopped by theengagement of ears on sideplates 38 with stops 39 that are carried by and are immovable withrespect to the housing Ill, said stops, as will presently appear, beingdirectly connected to thesupporting elements or rails along which thereservoir is moved between operative and inoperative positions. Theweight of the door is sufiicient to hold it open in opposition to thepower of the spring-33 when the door is at or near the lower. limit ofits movement.

Suitably secured, as by fastening means 45, to

the inner sides of the front and rear walls of the housing it, aresupporting elements or rails 46, one of which is shown in perspective inFig. 6. Each includes a wall engaging portion or plate 31, laterallyfrom the upper edge of which extends for a greater part of the length ofthe v erence to Patent No. 1,987,179, dated January element a track 48having spaced rectangular openings 49; and beyond the inner end of thetrack is a depressed laterally extending seat 59. Welded or otherwisesecured to the end of the portion 4! remote from the seat 59 is one ofthe previously mentioned stops 39. The track 48 is in the nature of arack by reason of the openings 49.

The reservoir 55, shown in perspective in Fig. 3, is, in the presentinstance, generally cylindrical in shape, its peripheral wall beingdesignated 56. According to the present construction, one of the endwalls is formed integral with the peripheral wall while the other,designated 58, is seamed to the edge of the peripheral wall. Both endwalls are provided with central bosses 59 that may be likened untotrunnions. They are shown in the present embodiment as cylindrical andas having suitably attached to their outer ends, as by welding orbrazing, plates 60. These plates are generally circular and are providedat diametrically opposite portions with series of lugs or teeth GI, andon one side, between the two series of teeth, with what may be termed afoot 62. It will be observed that the foot 62 of each plate 60 is inapproximate radial alignment with a filling and discharge opening in theperipheral wall of the reservoir that is surrounded by a threaded neck64 to which is applied a screw cap 65, and said cap is equipped with theusual valve 66 with which is associated in the customary way a spring 61that tends to hold the valve closed. The neck 64 that surrounds saidfilling and discharge opening is set within a depression 68 that servesto retain any liquid that may drip from the neck or cap when thereservoir is moved from inverted to upright position. The side of thereservoir opposite the filling opening is shown as flattened and ashaving applied thereto a base 69. Handles 10 are secured, as by rivetsH, to the peripheral wall 56 on opposite sides of the filling anddischarge opening, and to accommodate the fingers of the person handlingthe reservoir, the peripheral wall is formed with depressions 12 underthe handles. It may be explained while on the subject'of the reservoirthat except for manufacturing expediency, the lugs or teeth 6| and thefeet 62 might be made integral parts of the bosses 59, or might beapplied to the peripheral portions thereof as units. Because of theobvious character of such alternatives, illustration thereof is deemedunnecessary.

To replenish the oil supply of the stove, the door 39, grasped by thelug 31, is swung downwardly to the position shown in Fig. 5 where it isstopped by the engagement of the lugs on the plates 38 with the stops39. The person attending the stove reaches into the housing l0 throughthe open side thereof and draws the reservoir outwardly, as by means ofthe near handle 19, until the feet 62, sliding on the seats 50, engagethe inner ends of the tracks 46. The operator may then take hold of thereservoir and roll it out through the open side of the housing with thearcuate bearing portions of the plates 60 traversing the tracks 48, thelugs or teeth 6| entering the openings 49 to render positive thetraction between the bearing parts and tracks, as in the manner of arack and pinion. As the reservoir moves along the tracks 48, it ispositively turned over so that by the time the hearing portions run ofiof the outer ends of the tracks, the reservoir will be deposited insubstantially upright position on the door 30, the

base 69 of the reservoir resting upon elevated ribs or glides 15. Thereservoir may then be shifted along the door to a more convenientposition for lifting, as to the position shown in full lines in Fig. 5.The reservoir may now be carried away by means of the handles 10 andrefilled, and it, or a previously filled reservoir, may be placed uponthe door and pushed inwardly until stopped by engagement of one end ofthe base 69 with the hinged pintle 3|. This disposes the reservoir in aposition from which it may be swung over to bring the curved bearingedges of the plates 69 intocontact with the tracks 48 after whichfurther lateral pressure on the reservoir will cause it to roll overinto inverted position with its opening in discharging relation to thedistributing receptacle or basin l2; the lugs or teeth 6| againcooperating with the tracks in the manner above explained so as toinsure a properly inverted position of the reservoir and a dispositionof the feet 62 upon the seats 50. As the reservoir assumes thisposition, the valve that controls the discharge opening is unseated bycontact of the outer end of its stem with the bottom of the depressedportion l6 of the plate [5. Liquid will then flow into the reservoiruntil the level rises sufliciently to seal the opening by contact withthe cap 65. A liquid level is thus established which will prevailthroughout the system including the burner bowl or firepot 5, anyvariation in the oil level during operation of the burner being due tothe consumption of the fuel. After the reservoir is in place, the outerend of the door 30 may be lifted and the spring 33 will act to close itand hold it in closed position. Because the reservoir is symmetrical onboth sides of the radial plane of the filling and discharge opening,having the two series of lugs or teeth 6| on opposite sides of the feet62, no care need be exercised as to which side of the reservoir isadjacent the housing II] when placed upon the door 39.
